Team Fortress 2

Earlier this evening, as I played on the Payload server my clan hosts, every stinkin' time the Upward map loaded, within seconds the Payload disappeared and the final cap point appeared taken by BLU. However, a victory was not recorded for BLU, and in some cases RED 'successfully defended the map until time ran out,' and they recieved the victory.

The Payload wasn't actually gone, however; it merely disappeared. But if BLU players moved close enough to it, they would trigger the Payload to move. In one case, BLU managed to successfully push the Payload to the penultimate cap point, after which a victory was recorded for BLU.

This wasn't happening for any other map in the server's rotation. The clan leader was flummoxed. He investigated, and I was in the clan's TeamSpeak channel with him and a few other clan members when he figured it out:

Apparently if a RED Engineer builds a Teleporter close to the final cap point (whether this "works" in all Payload maps or just Upward I don't know) and uses it to teleport, AND bread falls into the pit (which isn't difficult), the system will register the bread as the Payload having fallen into the pit and give the point to BLU.

Oh, go me, I just figured out why it's only happening on Upward maps: THERE'S NO DOOR ON THE PIT IN UPWARD, it's too big! All other Payload maps have a door that opens JUST as the Payload is about to fall into the pit except for Upward.

So now we're all just playing in Upward watching bread cause this huge-♥♥♥ explosion in Upward.

I achieved such an effect in Garry's Mod by dropping a prop into the pit of Upwards final point on accident. Instant death explosion included. And the payload cart at the start also disappeared too. I think it may be a problem with the Bread's coding. Cause if it's treated as a physics prop as everything else in Garry's Mod is treated as, then it will cause the explosion everytime.
